🩺Executive summary

HealthLink is a decentralised platform that enables secure, fast and transparent exchange and usage of medical data. We use blockchain technology to create a user-focused electronic health record and maintain a single true version of the user’s data.

HealthLink will enable users to give conditional access to different healthcare agents such as doctors, hospitals, laboratories, pharmacists and insurers to interact as they see fit. Each interaction with their medical data is auditable, transparent and secure, and will be recorded as a transaction on HealthLink’s distributed ledger. During this process, the patient’s privacy is protected at all times. HealthLink is built on the permission-based Hyperledger Fabric architecture which allows varying access levels; users control who can view their records, how much they see and for what length of time. By empowering users, we can build the future of healthcare together. HealthLink will be a platform for other digital health applications to develop on; users will be able to sign for these applications and services which are powered by their health data and secured by smart contracts. HealthLink is currently developing two applications to work alongside the platform: a doctor-to-patient telemedicine application and a health data marketplace. The telemedicine application will enable users to consult a real doctor remotely (for example, on their phone) for a small fee payable directly to the doctor.

The Marketplace enables HealthLink users to negotiate commercial terms with third parties for alternative uses or applications of their personal health data. For example, putting forward their data to be used in medical research. It is intended that HealthLink and others will contribute many more applications to the platform - helping bring value to all stakeholders. HealthLink’s platform will be powered by “HTK”. The initial issuance is 100,000,000 pieces, and additional issuance will be carried out later based on ecological construction.
